Merge pull request #3403 from Segrain/dev

Atmospherics' pipe painter.
Moved code from parent class with checks to subclasses.
Lots of copypaste code, but better that bloating that one main function even more IMHO.
As for bloat reason - readded advanced medithingies. Work same as lesser ones, but heal some damage directly instead, and have different messages/
Capped regen from treated wounds at 50 damage.
If there is a wound with more than 50 damage, it only can be healed with chems or advanced medikits (if they heal it past 50 on their use).
Splints!
Actually added 2 commits before, but now with full capabilities.
Autoinjectors.
Now they are one-use, as they were intended.
You can still change their contents with syringes before they are used.
To mitigate their one-use nature, box of them is added to medical closets and supply pack.
Added advanced medikits.
